Ultraviolet B light is good for the gut microbiome

A small study published in the journal Frontiers in Immunologyon October 24, 2019, shows that exposure to ultraviolet B (UVB) light, which is commonly achieved through sunlight exposure, can trigger specific beneficial changes in the gut microbiome, which are dependent on the preceding serum levels of vitamin D.

Gut microbiome is a reality in fetal life also

A study published in the Journal of Clinical Investigation shows that in both mice and humans, the fetal gut has its own microbiome, which is probably derived straight from the maternal organism.

Unhealthy gut microbiome reduces brain synaptic pruning, impairs learning

A new study by Weill Cornell Medicine and Cornell University has come up with more explanations of how gut microbes communicate with the brain neurons. The study, published in the journal Nature on October 23, 2019, examined the brains of mouse models and found that when the gut microbiome is significantly reduced, there are changes in gene expression in the brain’s microglial cells.

Protein mutation that causes inflammatory bowel diseases becomes dysfunctional

A new study led by researchers at St. Michael's Hospital and the Princess Margaret Cancer Centre in Canada and Zhejiang University School of Medicine in China has uncovered why a protein mutation that causes inflammatory bowel diseases is dysfunctional.

Universal influenza vaccine developed at Cornell is set for human clinical trials

A universal influenza vaccine with the potential to be longer lasting and more effective than commercially available vaccines is destined for human clinical trials, thanks to a $17.9 million grant from the National Institute of Allergy and Infectious Diseases.

Cooperative research center at LLNL aims to develop vaccines for chlamydia

A cooperative research center that aims to develop vaccines for chlamydia has been established by the National Institutes of Health at Lawrence Livermore National Laboratory.

UChicago researchers reveal the secret of cancer-related Warburg effect

A new study, led by researchers at the University of Chicago, provides an answer to why cancer cells consume and use nutrients differently than their healthy counterparts and how that difference contributes to their survival and growth.

New method to turn wood into pharmaceutical ingredients

Production of hazardous waste during drug manufacturing is a serious concern for the pharmaceutical industry.

Disrupting key immune regulator boosts anti-tumor immunity, enables cancer clearance

The immune system must strike an exquisite balance between vanquishing infections and cancer, while at the same time restraining its activity to avoid inadvertently attacking the body's healthy tissues and organs.

Researchers discover conjugative plasmid that augments virulence in superbug

A recent research led by a scientist at City University of Hong Kong has discovered an easily transmitted DNA piece that can make a new type of hyper-resistant and deadly superbug become hyper-virulent quickly, posing an unprecedented threat to human health.

Half the drugs in use damage gut bacteria, says new study

A startling presentation at UEG Week 2019, in Barcelona, reveals that the gut microbiome is at high risk for damage each time we use a drug from one or more of 18 commonly used groups. The effects may range from changes in the relative proportions of different beneficial and potentially harmful species to alterations in the cellular metabolism of the bacteria themselves.

SEPATH: New template to detect oncogenic viruses and bacteria in human DNA

A new study from the University of East Anglia describes a novel approach to detecting bacteria and viruses that may possibly be causing cancer. Many such associations have already been found, such as HPV (human papilloma virus) infection in cervical cancer, and Helicobacter pylori (H. pylori) in stomach cancer.

E. coli bacteria study may provide clues about drug resistance

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife.

Taste neurons could be controlling feeding behaviour find researchers

Researchers from the University of California, Riverside used a common fruit fly (Drosophila melanogaster) to find the association between taste neurons and control of feeding behaviours. They noted that if they genetically modulated these flies, they could make them selectively avoid certain chemicals including acids, bitter compounds, salty substances etc. The results of their study appeared in the October issue of the journal Cell Reports.
